DI SPLAY yCOVER Filed March 25, 1955 Patentedl Feb. 12, Y 1935 *l Si PATENT* OFFICE? m1, Theseimprovements yrelate to a readily .attach-V able and removable'forin ofcoveradapted to be positioned upontheopen end portion of a box A containing biscuits, crackers or other articles, whereby therecepta'cle may be maintained closed u againstdustand dirt while its contents may be exposedrtothe purchasers View andbe readily reached as desired. j Covers forthese general pur- 'posesandfofv `the Vgeneral .character herein described,l are well known, andrreferenoe is made to my'eatents Massima-955 of June 1 9, 1923 and 1,511.1426 of Qctober 14,"19'24 in this connection. rlDisplay covers of this kind contain a transparent glass plate in the swinging lid. One of theV objects ofthe present invention is to provide improvedVT and vpeculiarly advantageous means `for holding that glass panel or plate while permitting itsfre'ady removability as for cleaning, and means whereby such a plate may Y readily be inserted,

both initially and should the one in use becomeVV broken. Another object is to `provide peculiarly advantageous hinge for'the'swinginglid. -Particular advantages of the constructions in these respects Willappear hereinafter.

In the drawing Figure lfis a Vpers'pective of a receptacle cover containing-these improvements; Fig. 2 is a vertical sectional` view, on an enlarged scale, as on"the`line2f2 'offFig.`-`1`;

Fig. s is ja 4teatri;viewer the iid, interinyV broken away and s howing'the'preferred form of as ontheline 6 6 of Fig. 1.

f Such receptacle coversr contain two main'parts,' namely .the body 1D and the lidll. Eachof theseY parts is formed'from thinsheet metal. The body has four depending flanges-12 adapted to Yt around the outside of theopen end portion of a receptacle fragmentarily shown and marked 14 in Fig. 2.A From these iianges 12 the bodyv extends inward at 15 to provide iiat surfaces which serve to limit the movement of the body upon against which thelid rests. Fig. 2 shows one of these parts 15 in section. Figs. 5 and 6 showV that the body is open interiorly, that opening being dened Vby beads 16 which are formed by turning the metal'of the part 15 around the Wire 17 which Wire 17 is to be understood as being a single V wire bent-into rectangular shape and then enthe receptacle, and they also provide surfaces` compassedbyV the sheet metal at 16 as'vshown.

The goods arereached through this opening dened by the continuous 'bead 16. Theconstruction lin that respect is Yold, and except for the glass-holding means and the-hinge, all that I show herein may be considered old. y

v Tur-ning to the lid 11,which is a rectangular sheet-metal frame, it has continuous` top surfaces land depending iianges 19the lower free edges `of these anges 19 being turned arounda wire 20. and 20a,vwhich wire 20, 20a may be considered a `single piece of wire bent'in rectangular shape and encompassed by the metal as shown. v

I- mark one part of this wire 20a because that part serves as a hinge pin for the lid. That wire has beenus'ed heretofore as a hinge pin, as by the provision of hinge lugs formed of strip metal passing around the wire atexposed portions thereof between vthe adjacent corners of the lid. The occasion Vfor the presen-t improvements arises from the fact that according` to olderv practice the hingingl occurred at portions of the body and lid` whicharequiteflexible. The movements Vof the lidi into the open position shown in Fig. 4 brings parts together at 21 limiting the movement of the'lid', andthe contactthere causes a leverage action lon Vthe hinge pin and hinge lugs and the body is bent or deformed through carelessmanip` ulation, and the operatoralso has a sense of iiim-l Vsines's of construction due to the springy give or yield which the lid has when it comes into its open and stopped position as in Fig. 4.v

IY overcome` these objections and provide anV unusually firm and rigid hinge connection for these lightweight and yielding vspringy bodies andV lids, and also reduce the number of hinge lugsV ordinarilyv used from three to two, and also simplify and-reducefthe cost of Vthe mechanical operations of making the. hinge connection, by providing a hinge lugat thecorners of the lid on one side,'as will be noted'frcmFig. l, where marked 24.'v This Vhinge Vstrap is secured as by a rivet upon the upper surface of the inwardlyturned'part 15 ofthe body closely adjacent to the associated corners of the body'and closely adjacent to and aligned with one Vside of the wire 17 and the rib 16 defining the inner opening of the body. 'I'he hinge straps also lap two ofthe adjacent sides of the wire andy bead 16-17. The hinges are thus secured at the strongest and most reinforced portions 4of the body and of the lid, and substantially where the spring or yield in each is the least.

Fig. 4 shows Vthat the hinge lug or strap 24 has vthe hinge lug or strap bent aroundthe4 wire is leaves 24a through which passes the rivet 25. It is to be noted furtherthat these straps 24a are within the vertical projection of the lid and are not exposed when the lid is closed, as in Fig. 1, and that no part of the hinge is then seen except the bent-around part 24, which is in appearance a continuation of the bead at that marginal edge.

So constructed and arranged, the hinge straps are aligned with one side each of both the body wire 17 and the Ylid wire 20a, and the lidrspans the two hinge straps as well as the side of the wire 17 which is aligned with the straps. Thus the parts stiffen and reinforce each other after the manner of a unitary beam which preventsl the usual deformation of the parts in the -vicinity of the hinge straps.

The other feature of improvement is in the means for holding the glass'panel 30, which isto be considered as of such rectangular shape and dimensions as to enable it to be accommodatedV V32 which has eyes 33 formed at its ends and rivets 34 pass through these eyes and hold the wire 32 xedly at its ends against the upper wall 19 of the lid frame. The rivets 34 in Fig. 1 show where these rivets occur when viewed from the outside. The wire 32 is in effect bowed toward the glass 34 and preferably presses against the glass at spaced-apart places, for example at 36, 36. The springy wire 32 is tensioned toward the glass, but when this spring device is made of wire and inthe general form shown it is desirable to increase the spring tension holding the glass, and to that end the wire is bent away from the contact points at 36, and the catch-engaging part 38 is formed in the wire adapted to reach back toward the flange 19 and to be engaged by the catch 39, which is in thel form of a lip pressed` out of the side wall or flange 19.

Fig. 2 shows that from the rivets 34 the wire is formed to extend away from the side wall or flange 19, the purpose of which is to get the contacting pointsas 36 so far away from the wall 19 that they Awill surely press upon the glass V.when the glass is not of the full length of the hollow interior of the lid, and preferably the glass is not of that full length but is say about an eighth of an inch short thereof at each Vend, whereby the glass will clear the wire when the wire is in open position.

' The construction is such that the operator presses the middle portion of the wire toward the glass to get the part 38 engaged by the catch, and

this puts additional spring pressure upon the wire, and the wire is held positively in position and develops spring pressure between the catch and each end of the wire. When it is desired to remove or insert the glass panel the wire devices are sprung free of their catches and moved into the dotted-line position shown in Fig. 3, where ,the tongue-like part 38 hangs upon the free edge of the lid in an out-of-the-way position and the glass can then simply be lifted away or inserted. Particular advantages of this construction are that the wire device is held firmly at both ends, and for one thing it cannot be separated and lost. In my former practice, as indicated by the patents mentioned, the wire device was mounted to swing-at one end. Such a wire could easily be bent out of shape, is morev or less in the operators way, and there is the possibility of some injury because of such a wire standing up in the air while the glass is being inserted or removed.

The present device calls for apparently the minimum amount of movement and thought on the part of the'operator and the operation is Y more simple and easy than in any other form of which I am aware. It is also stronger and in general more effective.A Furthermore, it reinforces the frame of the lid, and, together with .the pressure it exerts on the glass, it produces a combination of strainfresisting elements which give the lid as a ,whole greater strength and rigidity.

Claims to the Vpane-retaining means shown herein are divided'out hereof and are made in my copending application Serial No. 730,748, filed June 13, 1934.

I'contemplate asbeing included inthese improvements allrsuch variations and departures from what is thus specifically illustrated and described as fall within the scope of the appended claim.

I claim:

In a displayfcover of the class described, the combination with a rectangular body having a horizontal flat frame-like surface anda rectangular opening therethrough, said opening beingv margined by a wire extending therearound and thel body being bent around the wire forming a bead having parallel sides, of hinge straps riveted to the body adjacent two of the ,corners of the opening, both hinge straps being aligned with one of the sides of the bead Vand each hinge strap lapping one of the other adjacent sides of the bead, a lid spanning said bead and aligned hinge straps, said lid carrying a hinge pin passing through said straps at the corners of the lid, whereby the said straps are aligned with both the wires of the b'ody and ofthe lid and are within the vertical projection of the cover when closed and each of the parts reinforces the other in the nature of a unitary beam to prevent deformation ofthe parts.
